one MovEn Application filed August 23, mo. j Serial no. 477,443 I 1 p This invention relates to devices for shiftmg cars, particularly freight cars and the general object of the invention is to provide a car mover adapted to be driven by an electric motor and so arranged as to apply power I to a wheel of the car to shift the car slowly along the rails. V,

A further object is to provide a mechanism of this character which includes a wedge- 10 shaped prow carrying a wheel adapted to engage with the track and a wheel adapted to engage with one of the wheels of the car, and

the following description.

" My invention is illustrated in the accom-" panying drawings, wherein Figure 1 is a side elevation, partly broken away showing my improved car mover;

Figure 2 is a section on the ure 1.

Referringto these drawings, 10 designates a supporting frame which extends upwar and rearward and which in cross'section has the formof an inverted 1!. This is'formed at its forward extremity with a solid prow 11, the curved upper edge face 12 of-which is relatively wide and adapted to bear against the periphery this frame or housingis open as at 13, and carries a thrust bearing 14:. Mounted between the sidewalls of the housing are the upper and lower rolls 15 and 16. The upper roll is smooth and has a width approximately equal to the thread faceof the car wheel, the middle of the roll being formed with teeth 17. The lower roll '16 is knurled or otherwise formed so as to grip the rail A middle is also formed with gear teeth. Ex-

tending between the rolls is a-worm shaft 18- havingthe worm 19 engageable with the teeth onthe upper and lower rolls to rotate these upper and lower rolls. The-worm shaft is 5 mounted in the thrust slow and requiring a line 2 20f Figof the car wheel.
